Detailed Description

Delayed callbacks.

This class provides the capability to create and manage timers, allowing you to schedule time intervals in milliseconds and execute a specified callback function when the timer expires. It supports both re-usable timers and one-shot timers that can be automatically destroyed after timeout or cancellation.

Member Typedef Documentation

Callback

using Callback = std::function<void(LTimer*)>

Type definition for the timer's timeout callback function.

Parameters

timer

Pointer to the LTimer instance that triggered the callback.

Constructor & Destructor Documentation

LTimer()

LTimer ( const Callback &  onTimeout = nullptr )

noexcept

Construct a re-usable LTimer instance with the provided timeout callback.

Parameters

onTimeout

The callback function to be executed when the timer expires.

~LTimer()

~LTimer

(

)

Destructor for the LTimer class.

If the timer is destroyed while it is running, the associated callback function is not invoked.

Member Function Documentation

oneShot()

bool oneShot ( UInt32  intervalMs, const Callback &  onTimeout  )

staticnoexcept

Create a one-shot timer that is automatically started and destroyed on timeout or cancellation.

Parameters

intervalMs	The interval for the timer in milliseconds.
onTimeout	The callback function to be executed when the timer expires.

Returns

true on successfully, false otherwise.

setCallback()

void setCallback ( const Callback &  onTimeout )

inlinenoexcept

Set the callback function to be executed when the timer expires.

Parameters

onTimeout

The callback function to be executed when the timer expires.

interval()

UInt32 interval ( ) const

inlinenoexcept

Retrieves the interval of the timer in milliseconds.

Returns

The interval of the timer.

running()

bool running ( ) const

inlinenoexcept

Checks if the timer is currently running.

Returns

true if the timer is running, false otherwise.

cancel()

void cancel ( )

noexcept

Cancels the timer without invoking the callback.

If the timer was created with oneShot() it is destroyed and the onTimeout callback is not called.

stop()

void stop ( )

noexcept

Stops the timer invoking the callback immediatly.

If the timer was created with oneShot() it is destroyed after the callback is triggered.

start()

bool start ( UInt32  intervalMs )

noexcept

Starts the timer with the specified interval.

Note

Calling start() on an already started timer will restart the timer without calling the callback. If this method is called within the timeout callback the timer is restarted even if it was created using oneShot().

Parameters

intervalMs

The interval for the timer in milliseconds.

Returns

true if the timer successfully started, false otherwise.
